Capljina Pumped Storage Power Plant Bosnia and Herzegovina is a 440 MW hydro power station in Federation of Bosnia and Herzegovina, Bosnia and Herzegovina. It is operated by Elektroprivreda Hrvatske Zajednice Herceg Bosne (Elektroprivreda HZHB) [100%]. Based on its capacity (estimated), it can supply roughly 441k homes (estimated). It ranks #8 of 34 Bosnia and Herzegovina power plants by installed capacity. Commissioned in 1979, it is around 47 years old — long-established. As a non-combustion source, it has no direct CO₂ emissions from generation. In context, hydro supplies about 36.6% of Bosnia and Herzegovina's electricity; the national grid averages 571 gCO₂/kWh (43.6% low-carbon) (2025).

At 440 MW, Capljina Pumped Storage Power Plant Bosnia and Herzegovina is well above the median hydro plant in Bosnia and Herzegovina (114 MW). Technically it is described as pumped storage. Hydropower converts the energy of falling or flowing water into electricity; output depends on rainfall and reservoir level, and large dams also provide grid balancing and storage.

This hydro plant converts the energy of falling or flowing water through hydro turbines. It sits in a temperate oceanic climate (Köppen Cfb) — Northern Hemisphere, latitude 43.0°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 20% below the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.
Climate heat-demand index: 42/100 — this site sits in the mid third of the power plants we cover by heating degree-days.
Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.
For a plant’s outdoor hardware — heat-recovery steam generators (HRSG), expansion joints, valves, flanges and their insulation — the local climate sets how fast unprotected steel and coatings degrade. This site sits in a corrosive environment (estimated ISO 9223 class C4 — High), with humidity / wetness the leading environmental stress.
Higher environmental severity is exactly where protective removable insulation pays back most: a sheltered micro-climate slows corrosion, UV and thermal-cycling damage and extends outdoor hardware service life. This is an indicative site-climate context — not a condition assessment of any specific plant or operator.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
The #1 largest hydro power plant of 16 in Bosnia and Herzegovina by capacity.
Bosnia and Herzegovina has 16 hydro power plants in this dataset, together about 2,222 MW of capacity.
